BACKGROUND

1. Technical Field

The present disclosure relates to an image compensating apparatus andmanufacturing method thereof, and more particularly, to an imagecompensating apparatus disposed upon a display panel and manufacturingmethod thereof.

2. Description of Related Art

As the development of technology, display technical is more and moreemployed to communicate which is indispensable. Because display panelwith narrow border is more and more popular, the border of display panelis tended to be manufactured narrower. In a display panel, someelectronic units are disposed on the edge thereof, a narrow border isdisposed correspondingly to support the electronic unit, therefore, theborder can not be omitted. However, in some situation, in order toobtain a display panel of a relative large size, such as more than 200inches, for displaying much more various information, it may bemanufactured by a large number of serialization displays jointedtogether in a plane. The borders between two adjacent display panelsjointing together may reduce a displaying quality. So, the border ismanufactured narrower or un-visible, that is helpful for a signaldisplay panel, or a jointed display panels to eliminate non-displayregions, or display image on a screen larger than a reality displayregion of such display panels.

Therefore, there is room for improvement in the art.

DETAILED DESCRIPTION

Reference will now be made to the drawings to describe variousembodiments in detail.

FIG. 1 is a schematic, isometric view of a first embodiment of a displayof the present disclosure. The display 100 includes a display panel 10,an image compensating apparatus 110 set on the display panel 10, and asupport portion 120. FIG. 2 is a partial cutaway view of the display100. The display panel 10 defines a display region 11 and a non-displayregion 12 encircling a periphery of the display region 11. The imagecompensating apparatus 110 is set on display region 11 along a borderbetween the display region 11 and the non-display region 12. A coveringportion 115 of the image compensating apparatus 110 is extended to coverthe non-display region 12. The image compensating apparatus 110 is usedto enlarge a display area of the display region 11 to cover thenon-display region 12. The support portion 120 is set on the non-displayregion 11 to support the image compensating apparatus 110. In thisembodiment, the support portion 120 resists again the covering portion115 to support the covering portion 115. It is understood that, for ajoint display consisting of a number of display panels 10, the imagecompensating apparatus 110 is set at a border between two adjacentdisplay panels 10. In this embodiment, there are four image compensatingapparatuses 110 set on the non-display regions 12. Referring to a topview of FIG. 3, each of the image compensating apparatuses 110 is shapedas an isosceles trapezoid. The four image compensating apparatuses 110are connected end to end to form a rectangular frame. In the otheralternative embodiment, the support portion can be omitted.

Referring to FIG. 4, FIG. 4 is a cross-sectional view of FIG. 3 takenalong IV-IV line. The four image compensating apparatuses 110 are set ona border of the display region 11 and adjacent to the non-display region12. At the corner of the display region 11, two opposite ends of theimage compensating apparatuses 110 are connected end to end via aninclined end surface to form a closed compensating frame. An includedangel between the inclined end surface and a periphery of the display100 is preferred to be 45 degree.

In this embodiment, the image compensating apparatus 110 is a triangularprism with a cross section shaped as an obtuse triangle. The supportportion 120 is a prism with a side surface resisting again the imagecompensating apparatus 110. The image compensating apparatus 110includes a light emitting surface 112, a light incident surface 113, andan inclined surface 114. In this embodiment, the light incident surface113 is a bottom surface contacting with the display panel 10. The lightemitting surface 112 inclines to the light incident surface 113. Thelight incident surface 113, the light emitting surface 112, and theinclined surface 114 are connected with each other. The light incidentsurface 113 and the inclined surface 114 from an obtuse triangletherebetween. The obtuse angle is preferred to be 135 degree. Aprojection of the light emitting surface 112 on the light incidentsurface 113 is greater than an area of the light incident surface 113.

The image compensating apparatus 110 includes a number of light guidingchannels 111. In this embodiment, each of the light guiding channels 111is a light guiding fiber. Because a light path of each light guidingfiber is independent from the light path of the other light guidingfiber, the light passing through each light guiding fiber do not disturbwith the light passing through the other light guiding fiber. Each ofthe light guiding fibers extends from the light incident surface 113 tothe light emitting surface 112. An extending direction of the lightguiding fibers is parallel to the inclined surface 114. Each of thelight guiding channels 111 extends along a substantially same direction.The light guiding channels 111 are arranged as a matrix.

In this embodiment, a width of the non-display region 12 is presented asW1. The bottom width of the support portion 120 is also W1. Both of aheight of the support portion 120 and a height of the image compensatingapparatus 110 are presented as W3. A bottom width of the imagecompensating apparatus 110 is presented as W2. The W2 is greater thanthe W1. Preferably, the W2 is a double of the W1. For example, when theW1 is 3 millimeters (mm), the W2 is 6 mm.

The display region 11 includes a number of pixels. Light from the pixelsis enter the image compensating apparatus 110 via the light incidentsurface 113 and emits out from the light emitting surface 112. Becausethe projection of the light incident surface 112 on the display panel 10is greater than the area of the light incident surface 113, an image ofthe display region 11 covered by the light incident surface 113 istransmitted to the light emitting surface 112 covering the non-displayregion 12. Thus, the non-display region 12 is invisible to a viewer. Thedisplay 100 has a frame-less effect.

FIG. 5 is a schematic, isometric view of a second embodiment of adisplay 200. The display includes a display panel 20 and an imagecompensating apparatus 210 set on the display panel 20. A differencebetween the image compensating apparatus 210 of the second embodimentand the image compensating apparatus 110 of the first embodiment is thatthe image compensating apparatus 210 includes a number of elongated sideimage compensating apparatuses 211 and a number of corner imagecompensating apparatuses 212. A display effect of four corners of thedisplay 200 is improved by the corner image compensating apparatuses212.

Referring to FIGS. 6 and 7, two adjacent side image compensatingapparatuses 211 are connected via one of the corner image compensatingapparatuses 212. Referring to a top view of FIG. 6, four side imagecompensating apparatuses 211 and four corner image compensatingapparatuses 212 are alternatively connected end to end to form arectangular closed frame. The corner image compensating apparatuses 212are correspondingly located at four corner of the display region 21.

Referring to FIG. 7, the side image compensating apparatus 211 includesa number of light guiding channels 2111 arranged as a matrix. In thisembodiment, each of the light guiding channels 2111 is a light guidingfiber with an even diameter. The light guiding channels 2111 extend fromthe light incident surface 213 to the light emitting surface 214. Thelight guiding channels 2111 are parallel to the inclined surface 114. Alight from the display region 21 enters the image compensating apparatus210 from the light incident surface 213 and emits out of the imagecompensating apparatus 210 by passing through the light guiding channels2111. Thus, the viewer can see the image on the light emitting surface214.

Referring to FIGS. 8 and 9, each of the corner image compensatingapparatuses 212 includes a light output surface 2122, a light inputsurface 2123, and a sloping surface 2124. The light input surface 2122includes a pair of interconnecting sub-output surfaces 2122 a and 2122b. Preferably, the sub-output surface 2122 a is not coplanar with theother sub-output surface 2122 b. In this embodiment, the pair of thesub-output surfaces 2122 a and 2122 b forms an included obtuse angle. Inthis embodiment, the light input surface 2123 is a bottom surface of theimage compensating apparatus 210 contacting with the display region 21.The sloping surface 2124 includes a pair of interconnecting sub-surfaces2124 a and 2124 b. The sloping surface 2124 correspondingly connectswith the light output surface 2122 and the light input surface 2123. Thesub-output surfaces 2122 a and 2122 b are inclined to the light inputsurface 2123. The sub-surfaces 2124 a and 2124 b correspondingly form anobtuse angle with the light input surface 2123. Preferably, the obtuseangle is 135 degree.

Each of the corner image compensating apparatus comprises a number oflight guiding channels 2121. Each of the light guiding channels 2121 iscombined with a number of alveolate light guiding fibers. The lightguiding fibers extends from the light input surface 2123 to thesub-output surfaces 2122 a and 2122 b. A diameter of the light guidingfibers of the corner image compensating apparatus 211 graduallyincreases in the extending direction. In detail, referring to acoordinate system of FIG. 8, when the light guiding fiber extends alonga Z axis, radius of the light guiding fiber in X axis and Y axis aregradually increased. Also referring to FIG. 10, a cross-sectional areaof the light guiding fiber gradually increases in the extendingdirection.

Because the projection of the light output surface 2122 on the displaypanel 20 is greater than the area of the light input surface 2123, animage of the display region 21 covered by the light input surface 2123is transmitted to the light output surface 2122 covering the non-displayregion 22. Thus, the non-display region 22 is invisible to a viewer. Thedisplay 200 has a frame-less effect.
